Quality will shine through. On of my current favorite authors goes by Vaughn Heppner, and spent many years trying the traditional route till e publishing. His topics would never be touched by a traditional house, similar to yours.
Wow, I just looked, VH is quite prolific! It takes me 2-3 years to write my novels. I am not a sc-fi buff, but I’m glad that ebooks are allowing a lot of unpublished authors to have a fair shot. After that, “quality will out.”
But all we ever wanted was a fair shot. Thank you, Jeff Bezos!
